Answer:
Step-by-step explanation:
I didn’t see any choices but an inverse function switches the x and y values.
For every (x,y) of f(x) the inverse function will have (y,x) of f^-1(x)
Answer:
4/3 or 1 1/3
Step-by-step explanation:
cube root of 64 = 4
cube root of 27 is 3
4/3 or 1 1/3
ANSWER
EXPLANATION
This means the opposite side is 3 units and the hypotenuse is 4 units.
We use Pythagoras Theorem to find
Answer:
Θ = 124°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n - 5, thus
sum = 180° × 3 = 540°
Sum the given interior angles and equate to 540
2x - 3 + 2x + 7 +3x - 4 + 3x - 4 + 3x - 2 = 540, that is
13x - 6 = 540 ( add 6 to both sides )
13x = 546 ( divide both sides by 13 )
x = 42
Thus
Θ = 3x - 2 = 3(42) - 2 = 126 - 2 = 124°
Let's denote a variable to the number as x. Then, let's slowly decipher the verbal descriptions into algebraic expressions:
Nine times a number added to -5: 9x + ⁻5 = 9x - 5
<span>twice the sum of nine times a number and two: 2(9x+2)
Let's subtract the first expression to the second expression:
</span>2(9x+2) - (9x - 5)
<span>Next, let's simplify the expression.
18x + 4 - 9x + 5
9x + 9
The final expression would be 9x + 9, or nine times a number added to nine.
